The screwdriver seems to have originated in either France or Germany in the late 15th century. The original name for this tool was screwturner or turnscrew. The earliest screwdrivers had pear-shaped wooden handles and were made for slotted screws. Screws were used in the 15th century for constructing screw-cutting lathes, for securing breastplates, backplates and helmets on medieval jousting armor. Screwdrivers developed over time as the development of screws evolved and improved.
Grip of the cordless screwdriver can be made of reinforced plastic or rubber. While not completely protecting you from a possibility of an electrical shock, rubberized grip on cordless power tools is safer and more comfortable
Size and weight are essential to consider and depend on the amount and type of usage. However, what is more important to consider is the balance of the cordless screwdriver - how well it's chuck points straight ahead and doesn't tilt when you operate power tool.
